User Manual V1.0
Thank You for Choosing Orange
Ever since the founding of the company in 1968, Orange has been a pioneering force in the guitar amplification industry. Today, with a team of the world’s finest amplifier engineers, Orange continues to push back the boundaries of conventional valve amplifier design.
Our commitment to craftsmanship and quality control has allowed our amplifiers to stand the test of time, giving their owners as much pleasure now, as the day they were bought. To maintain this level of excellence, each Orange amplifier is put through many rigorous test procedures before leaving the factory.
The warmth, tonal quality and rich harmonics generated by a valve amplifier cannot be reproduced by ‘artificial’ means. Many guitarists have reached the same conclusion: neither the transistor nor the microchip is a true alternative to valve technology.
This manual contains valuable technical and safety information. Please take the time to read this manual as the information may enhance the sound and performance of your amplifier. We are confident that you will be delighted with your new purchase and that it will provide you with many years of enjoyment. You are now a member of the Legendary British Guitar Amplifier Owners Club!
In the interests of product improvement, the contents of this manual may be subject to change without notice.

BEFORE USING YOUR AMPLIFIER
Always ensure the amp’s volume control(s) are set to zero before switching on the power to amplifier.
To prevent hum and electrical noise operate your amplifier and instruments as far away from other electronic devices (especially fluorescent and neon lamps) as possible as these generate extremely high levels of electronic noise.
Make sure the correct speaker load is connected at all times during operation in one of the following configurations:
• 1 x 8 Ohm cabinet – Use either speaker output (rear panel).
• 2 x 8 Ohm cabinets – Use both speaker outputs (rear panel).
• 1 x 4 Ohm cabinet – Use either speaker output (rear panel).
IMPORTANT NOTES FOR CONNECTING SPEAKER CABINETS:
• Do not use two speaker cabinets of mismatched impedance!
• Do not connect a speaker load which is less than 4 Ohms!
• Always connect to a speaker cabinet(s) of suitable power handling!
• Only connect speakers using a quality dedicated Speaker cable. Never use an instrument cable!
Failure to observe these points may cause damage to both the amp and cabinet(s).
When powering up, ensure the amplifier is set to the STBY position on the front panel for a minimum of two minutes prior to performance. This will prolong the life of the valves.
The HT Fuse(s) (rear of chassis) will blow in the event of output valve failure in order to protect the internal circuitry from damage. Orange recommends output valves are replaced in full matched sets. Orange models fitted with EL34 or 6550 valves will also benefit from a bias adjustment which should only be undertaken by a qualified technician. When changing the HT fuse, gently push down on the fuse holder and turn anticlockwise to release the fuse.
Switches mains power to the amplifier on/off. Connect the supplied IEC/Mains cord to the AC Mains inlet (rear). The power LED will illuminate when the mains switch is set to ON. Set the VOL. control to zero/minimum before switching on power to the amplifier.
Adjusts the overall output volume level.
Adjusts the high frequency response. Increase the treble for brighter tones or reduce for a warmer sound.
Adjusts the midrange response. Increasing the mids creates a fatter sound, whilst reducing ‘scoops’ the tone.
Adjusts the lower frequency response. Increasing the bass produces deeper sounds.
Controls the (preamplifier) gain level. Higher settings produce more
distortion. Note: When set to minimum, no sound will be heard.
The clean switch gives more headroom and smoother, clean sounds.
The pad switch on the front is for active basses which takes 6dB off the input sensitivity.
Use a quality shielded instrument cable to connect your instrument to the INPUT jack socket. The PAD switch (-6dB) selects the correct input level for instruments with active or passive pickups.
Rear Panel Features
|1. Speaker Outputs||Refer to ‘Before Using Your Amplifier’. Make sure the correct speaker load and power handling is connected or that the DI is connected!|
Total minimum impedance = 4Ω (Ohms). Speaker outputs are wired in parallel (Speakon connector only).
Full output power = 500 Watts @ 4Ω (Ohms).
|2. Speaker Impedance Switch||Make sure this switch matches your speakers impedance.|

VALVES AND FUSES CAN FAIL AT ANY TIME!
From time to time output and preamp valves may fail. For optimum performance, we recommend output valves are renewed at least once a year. All Class A/B models (50 Watts and above) will benefit from having the bias checked and adjusted when output valves are changed. This should only be carried out by a qualified engineer.
Orange amps are protected from damage caused by valve failure and inconsistent mains voltage by various fuses. We recommend that Orange users have a set of spare valves and fuses.
